Answer:
A. volume and D. mass
Explanation:
Density is the amount of matter (mass) in a given space (volume).
The density of an object can be found using the following formula:
d=m/v
where m is the mass and v is the volume.
In order to find the density, you must know the mass and the volume of the object.
Therefore, the correct answers are A. volume and D. mass.
